From the GENI website:"GENI, the Global Environment for Network Innovations, is a proposed national facility that supports exploration of radical designs for a future global networking infrastructure. It will be a research network/testbed that is geographically distributed, contains diverse devices including wireless, supports many simultaneous experimenters, and allows end-users to use and exploit those experimental protocols."ProtoGENI is a smaller, less fancy, but functional version of both theGENI software and deployed hardware. We are primarily deriving it fromour Emulab software, and secondarily leveraging the existing Planetlabsoftware. Both base systems are production code.
